Description

BACKGROUND

This specification relates to data processing systems implemented on computers, and more particular to data processing systems providing services in the nature of web services.

Enterprise software systems are generally large and complex. Such systems can require many different components, distributed across many different hardware platforms, possibly in several different geographical locations. Thus, the architecture of a large software application, i.e., what its components are and how they fit together, is an important aspect of its design for a successful implementation.

Web services are one technology for making the functionality of software applications available to other software, including other applications. A web service is a standards-based way of encapsulating the functionality of an application that other applications can locate and access. A service-oriented architecture is a distributed software model within which functionality is defined as independent web services. Within a service-oriented architecture, web services can be used in defined sequences according to business logic to form applications that enable business processes.

SUMMARY

This specification describes a services architecture design that provides enterprise services having supplier relationship management functionality at the level of an enterprise application. Enterprise services are web services that have an enterprise-level business value.

In its various aspects, the invention can be embodied in systems, methods, and computer program products. For example, a system in one embodiment implements a services architecture design that provides enterprise services having supplier relationship management functionality at the level of an enterprise application. The design includes a set of service operations, process components, and optionally deployment units. Suitable business objects are also described.

The subject matter described in this specification can be implemented to realize one or more of the following advantages. Effective use is made of process components as units of software reuse, to provide a design that can be implemented reliably in a cost effective way. Effective use is made of deployment units, each of which is deployable on a separate computer hardware platform independent of every other deployment unit, to provide a scalable design. Service interfaces of the process components define a pair-wise interaction between pairs of process components that are in different deployment units in a scalable way.

Details of one or more implementations of the subject matter described in this specification are set forth in the accompanying drawings and in the description below. Further features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION

FIGS. 1A and 1B collectively illustrate a high-level view of a software architectural design, and of application software implementations of the design, that provides a suite of enterprise service operations, which can be organized into interfaces, having supplier relationship management application functionality.

The elements of the architecture include the business object, the process component, the service operation (or simply, the operation), the service interface, the message, and the deployment unit. The elements can also include process agents and reuse service components. These will be generally described below.

In one implementation, the software is implemented to be deployed on an application platform that includes a foundation layer that contains all fundamental entities that can used from multiple deployment units. These entities can be process components, business objects or reuse service components. A reuse service component is a piece of software that is reused in different transactions. A reuse service component is used by its defined interfaces, which can be, e.g., local APIs (Application Programming Interfaces) or service interfaces.

The architectural design is a specification of a computer software application, and elements of the architectural design can be implemented to realize a software application that implements enterprise application service interfaces. The elements of the architecture are at times described in this specification as being contained or included in other elements; for example, a process component is described as being contained in a deployment unit. It should be understood, however, that such operational inclusion can be realized in a variety of ways and is not limited to a physical inclusion of the entirety of one element in another.

The architectural elements include the business object. A business object is a representation of a type of a uniquely identifiable business entity (an object instance) described by a structural model. Processes operate on business objects.

A business object represents a specific view on some well-defined business content. A business object represents content, and instances of business objects include content, which a typical business user would expect and understand with little explanation. Whether an object as a type or an instance of an object is intended by the term is generally clear from the context, so the distinction will be made explicitly only when necessary. Properly implemented, business objects are implemented free of redundancies.

Business objects are further categorized as business process objects and, master data objects, mass data run objects, dependent objects, and transformed objects. A master data object is an object that encapsulates master data (i.e., data that is valid for a period of time). A business process object, which is the kind of business object generally found in a process component, is an object that encapsulates transactional data (i.e., data that is valid for a point in time). A mass data run object is an application object that executes an algorithm for a particular mass data run. An instance of a mass data run object contains a particular set of selections and parameters. A mass data run object implements an algorithm that modifies, manages, and/or processes a large amount of data in multiple transactions, possibly but not necessarily with parallel processing. A dependent object is a business object used as a reuse part in another business object. A dependent object represents a concept that cannot stand by itself from a business point of view. Instances of dependent objects only occur in the context of a non-dependent business object. A transformed object is a transformation of multiple business objects for a well-defined purpose. It transforms the structure of multiple business objects into a common structure. A transformed object does not have its own persistency. The term business object will be used generically to refer to a business process object and a master data object, unless the context requires otherwise. Properly implemented, business objects are implemented free of redundancies.

The architectural elements also include the process component. A process component is a software package that realizes a business process and generally exposes its functionality as services. The functionality contains business transactions. A process component contains one or more semantically related business objects. Any business object belongs to no more than one process component.

Process components are modular and context-independent. That they are context-independent means that a process component is not specific to any specific application and is reusable. The process component is the smallest (most granular) element of reuse in the architecture.

The architectural elements also include the operation. An operation belongs to exactly one process component. A process component generally has multiple operations. Operations can be synchronous or asynchronous, corresponding to synchronous or asynchronous process agents, which will be described below. An operation is the smallest, separately-callable function, described by a set of data types used as input, output, and fault parameters, or some combination of them, serving as a signature. For convenience in supporting use of the operations supported by a system implementing elements of the design, such a system can optionally include a repository of service descriptions that includes a standards-based description of each of the supported service operations.

The architectural elements also include the service interface, which may be referred to simply as an interface. An interface is a named group of operations. Each operation belongs to exactly one interface. An interface belongs to exactly one process component. A process component might contain multiple interfaces. In one implementation, an interface contains only inbound or outbound operations, but not a mixture of both. One interface can contain both synchronous and asynchronous operations. All operations of the same type (either inbound or outbound) which belong to the same message choreography will preferably belong to the same interface. Thus, generally, all outbound operations to the same other process component are in one interface.

The architectural elements also include the message. Operations transmit and receive messages. Any convenient messaging infrastructure can be used. A message is information conveyed from one process component instance to another, with the expectation that activity will ensue. An operation can use multiple message types for inbound, outbound, or error messages. When two process components are in different deployment units, invocation of an operation of one process component by the other process component is accomplished by an operation on the other process component sending a message to the first process component.

The architectural elements also include the process agent. Process agents do business processing that involves the sending or receiving of messages. Each operation will generally have at least one associated process agent. A process agent can be associated with one or more operations. Process agents can be either inbound or outbound, and either synchronous or asynchronous.

Asynchronous outbound process agents are called after a business object changes, e.g., after a create, update, or delete of a business object instance.

Synchronous outbound process agents are generally triggered directly by a business object.

An output process agent will generally perform some processing of the data of the business object instance whose change triggered the event. An outbound agent triggers subsequent business process steps by sending messages using well-defined outbound services to another process component, which generally will be in another deployment unit, or to an external system. An outbound process agent is linked to the one business object that triggers the agent, but it is sent not to another business object but rather to another process component. Thus, the outbound process agent can be implemented without knowledge of the exact business object design of the recipient process component.

Inbound process agents are called after a message has been received. Inbound process agents are used for the inbound part of a message-based communication. An inbound process agent starts the execution of the business process step requested in a message by creating or updating one or multiple business object instances. An inbound process agent is not the agent of a business object but of its process component. An inbound process agent can act on multiple business objects in a process component.

Synchronous agents are used when a process component requires a more or less immediate response from another process component, and is waiting for that response to continue its work.

Operations and process components are described in this specification in terms of process agents. However, in alternative implementations, process components and operations can be implemented without use of agents using other conventional techniques to perform the functions described in this specification.

The architectural elements also include the deployment unit. A deployment unit includes one or more process components and, optionally, one or more business objects, that are deployed together on a single computer system platform. Conversely, separate deployment units can be deployed on separate physical computing systems. For this reason, a deployment unit boundary defines the limits of an application-defined transaction, i.e., a set of actions that have the ACID properties of atomicity, consistency, isolation, and durability. To make use of database manager facilities, the architecture requires that all operations of such a transaction be performed on one physical database; as a consequence, the processes of such a transaction must be performed by the process components of one instance of one deployment unit.

The process components of one deployment unit interact with those of another deployment unit using messages passed through one or more data communication networks or other suitable communication channels. Thus, a deployment unit deployed on a platform belonging one business can interact with a deployment unit software entity deployed on a separate platform belonging to a different and unrelated business, allowing for business-to-business communication. More than one instance of a given deployment unit can execute at the same time, on the same computing system or on separate physical computing systems. This arrangement allows the functionality offered by a deployment unit to be scaled to meet demand by creating as many instances as needed.

Since interaction between deployment units is through service operations, a deployment unit can be replaced by other another deployment unit as long as the new deployment unit supports the operations depended upon by other deployment units. Thus, while deployment units can depend on the external interfaces of process components in other deployment units, deployment units are not dependent on process component interactions (i.e., interactions between process components involving their respective business objects, operations, interfaces, and messages) within other deployment units. Similarly, process components that interact with other process components or external systems only through messages, e.g., as sent and received by operations, can also be replaced as long as the replacement supports the operations of the original.

Interactions between process components that occur only within a deployment unit are not constrained to using service operations. These can be implemented in any convenient fashion.

In contrast to a deployment unit, the foundation layer does not define a limit for application-defined transactions. Deployment units communicate directly with entities in the foundation layer, which communication is typically not message based. The foundation layer is active in every system instance on which the application is deployed. Business objects in the foundation layer will generally be master data objects. In addition, the foundation layer will include some business process objects that are used by multiple deployment units. Master data objects and business process objects that should be specific to a deployment unit are preferably assigned to their respective deployment unit.
